Description

Technical Field

[0001] This utility model relates to the technical field of salt spray test equipment, and in particular to a sample placement structure for a salt spray test chamber. Background Technology

[0002] With the development of material corrosion testing technology, salt spray test chambers have been widely used as key equipment for evaluating the corrosion resistance of materials. Traditional salt spray test chambers simulate the marine salt spray environment by constructing a sealed cavity, and their sample holders generally adopt a fixed structure design, using a regular shelf structure to support batches of samples.

[0003] In related technologies, the sample holder mainly adopts an integrated welded frame combined with a tray structure. Although this design can achieve batch placement of samples, the method of fixing samples through preset holes has significant limitations. The bearing surface of the tray adopts a closed plate shape, which is not conducive to salt spray circulation, resulting in poor test effects and affecting the uniformity of test results. In addition, the fixed shelf is not adjustable and cannot be adapted to irregularly shaped samples of different sizes and shapes, resulting in low space utilization. These defects have gradually become technical bottlenecks restricting the development of material corrosion testing technology. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a sample placement structure for a salt spray test chamber, which allows for adjustable sample height, uniform contact between the sample and salt spray within the test chamber, and optimizes the diffusion path of salt spray particles.

[0005] The technical solution adopted in this utility model is as follows: A sample placement structure for a salt spray test chamber, comprising:

[0006] Base assembly, used for mounting support components;

[0007] The support component is fixed to the base component at its bottom by a threaded connection and assembled with the tray component at its top.

[0008] The tray assembly, threadedly engaged with the support assembly, is used to support the sample to be tested;

[0009] A drive motor is located below the base assembly. Its output end is connected to a connecting piece via a coupling. The other end of the connecting piece is connected to the bottom of the base assembly. The drive motor is used to drive the base assembly to rotate.

[0010] A protective component is disposed outside the drive motor to prevent salt spray corrosion of the drive motor.

[0011] In one embodiment, the base assembly includes a base body, the top surface of which has at least one mounting hole, and the inner surface of the mounting hole has threads.

[0012] In one embodiment, the support assembly includes a support rod, the bottom of which is threadedly connected to the base body through the mounting hole, and a support mounting part is provided at the top, the outer surface of which is threaded.

[0013] In one embodiment, the support rod is configured as a telescopic structure for adjusting the height of the tray assembly.

[0014] In one embodiment, the pallet assembly includes a pallet body, the bottom of which is threadedly connected to the support assembly.

[0015] In one embodiment, the contact surface between the tray body and the sample to be tested is provided with a rubber pad to increase friction and prevent sample displacement.

[0016] In one embodiment, the tray body has multiple through holes for salt spray particles to pass through, thereby optimizing the diffusion path of the salt spray particles.

[0017] In one embodiment, the protective assembly includes a protective housing with an openable and closable access door on one side for accessing and maintaining the internal drive motor.

[0018] In one embodiment, the output shaft of the drive motor is connected to the coupling via a keyway.

[0019] In one embodiment, the coupling is configured as a flexible coupling to buffer the vibration of the drive motor.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model has a compact structure. The base, support rod and tray are all connected by threads, which simplifies the installation and disassembly process, facilitates quick replacement or expansion of components, and reduces maintenance costs. In addition, the tray body has through holes, which breaks the traditional closed tray design, promotes uniform flow of salt spray, ensures the uniformity of sample contact with salt spray, and improves the accuracy of test results.

[0022] This utility model also has the following advantages:

[0023] (1) The present invention provides a rubber pad on the contact surface of the tray, which effectively prevents the sample from shifting due to centrifugal force when the drive rotates by increasing the friction force, thus ensuring the stability of the test process and the reliability of the data.

[0024] (2) The protective shell of this utility model encloses the drive motor, preventing salt spray corrosion and extending the equipment life; the inspection door facilitates maintenance, taking into account both protection and ease of operation;

[0025] (3) The support rod of this utility model adopts a telescopic structure and is combined with a threaded connection to realize flexible adjustment of the sample height and improve space utilization. At the same time, when the sample size is different, the tray assembly can be disassembled to match the corresponding size and model, which improves the applicability. Attached Figure Description

[0040] like Figures 1-3 The accompanying drawing shows a schematic diagram of the sample placement structure for a salt spray test chamber according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0041] In this embodiment, a sample placement structure for a salt spray test chamber is provided, including a base assembly 100, a support assembly 200, a tray assembly 300, a drive motor 700, a coupling 500, a connector 600, and a protective assembly 400. The base assembly 100 is threadedly connected to the support assembly 200, the tray assembly 300 is mounted on the top of the support assembly 200, the drive motor 700 drives the base assembly 100 to rotate through the coupling 500 and the connector 600, and the protective assembly 400 encloses the drive motor 700 to isolate it from salt spray corrosion.

[0042] In this embodiment, the base assembly 100 includes a base body 110, which is a disc-shaped structure with a plurality of mounting holes 120 evenly distributed circumferentially on its top surface. The inner surface of the mounting holes 120 is provided with internal threads. A connecting hole is provided at the center of the bottom of the base body 110 for fixing with the connecting member 600 by bolt.

[0043] In this embodiment, the support assembly 200 includes a support rod 210 and a support assembly part 220; the support rod 210 is a telescopic metal rod with an external thread at the bottom, and is threaded to the base body 110 through the screw-in assembly hole 120.

[0044] Furthermore, a support assembly 220 is welded to the top of the support rod 210, and the outer surface of the support assembly 220 is provided with external threads; for example, the support rod 210 may be equipped with a locking member (not shown in the figure) to fix the adjusted height.

[0045] In this embodiment, the tray assembly 300 includes a tray body 310, a rubber pad 320, and through holes 330; wherein, the tray body 310 is a circular metal disc with a threaded hole at the center of its bottom, which is connected to the external thread of the support assembly part 220; a layer of rubber pad 320 is bonded to the upper surface of the tray body 310 to increase the friction with the sample to be tested; a plurality of through holes 330 are evenly provided on the tray body 310;

[0046] Specifically, the aperture of the through-hole 330 is 5 mm to promote uniform diffusion of salt spray.

[0047] In this embodiment, the drive motor 700 is fixed below the base assembly 100, and the output shaft of the drive motor 700 is connected to the coupling 500 through a keyway. The other end of the coupling 500 is fixed to the bottom of the base body 110 by bolts through the connector 600.

[0048] Furthermore, after the drive motor 700 is powered on, it drives the base assembly 100 and the support assembly 200 to rotate as a whole through the coupling 500 and the connecting piece 600, which in turn drives the tray assembly 300.

[0049] In this embodiment, the protective component 400 includes a protective housing 410 and an inspection door 420; wherein, the protective housing 410 is a sealed metal housing that encloses the drive motor 700.

[0050] The protective housing 410 has an openable and closable maintenance door 420 on one of its side walls. The maintenance door 420 is connected by a hinge, and a sealing strip is provided at the contact end between the edge of the maintenance door 420 and the protective housing 410. The drive motor 700 can be maintained or replaced after the maintenance door 420 is opened.

[0051] Furthermore, the surface of the protective housing 410 is coated with an anti-corrosion coating.

[0052] In practice, the workflow of this utility model is as follows:

[0053] For sample installation, place the sample to be tested on the rubber pad 320 of the tray body 310, and adjust the extension length of the support rod 210 according to the sample height requirements.

[0054] When the salt spray test is started, the drive motor 700 drives the base assembly 100 to rotate, and the tray assembly 300 moves accordingly. Under the action of centrifugal force, the sample is kept stable by the friction of the rubber pad 320. During the salt spray propagation process, the through hole 330 can also optimize the dispersion path, thereby uniformly contacting the sample surface.

[0055] The maintenance procedures for this utility model are as follows:

[0056] Regularly open the inspection door 420 to check the operating status of the drive motor 700. If necessary, the coupling 500 or the connecting piece 600 can also be replaced.

[0057] This utility model has a reasonable structure, which realizes the adjustable height of the sample test. It can be adapted to samples of different sizes and specifications through the detachable tray. The through hole 330 on the tray makes the salt spray diffusion uniform, which significantly improves the accuracy and applicability of the salt spray test.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
